BlackBerry has a lot riding on the success of its new BlackBerry 10 smartphones. The company has already seen some moderate sales success with the new BlackBerry Z10 smartphone by selling three times better than previous BlackBerry models in the UK. While these devices have only recently launched, the manufacturer has already offered up its first firmware update for BlackBerry 10 devices.

The software update brings BlackBerry 10 to version 10.0.10.85 and the manufacturer says that the update is based on customer feedback. The update is available right now on some carriers and BlackBerry says it's working with all carrier partners to get the update available as soon as possible.

BlackBerry has a list of the top five improvements in the updated operating system. First of the top five improvements is improved performance for third-party applications. BlackBerry promises that this improvement will allow developers to build apps that run fast and smooth for end-users. The second update includes improvements to the phone, calendar, and contacts features including fixes for Gmail calendars.

BlackBerry has optimized the camera for better photos in low light situations, getting better performance in instances where users don't use the flash. Another important update in the firmware is tweaks to the browser and media functionality of BlackBerry 10 devices. BlackBerry has made improvements to the software and the way the browser handles video playback to provide an improved user experience.

The final and perhaps most important change in the new firmware update is a number of new battery life optimizations. BlackBerry says that it has added over 60 battery saving improvements since BlackBerry 10 devices launched. The manufacturer also says that heavy phone users should see longer average usage per charge cycle.

The download is about 150 MB in size and the software is available over the air. Users can manually check to see if the update is available under Settings/Software Updates/Check for Updates.
